Didn't we start with 5 at the back the last time we got pumped by Liverpool? Only for sources close to the dressing room to complain it was too unfamiliar to them and they hadn't had time to practice it and that's why Liverpool slaughtered us?
I also remember we started with five at the back at home against City, which basically made it into an attack vs defence training ground exercise for them.
Five at the back is not the answer people think it is.
As for the leaks, it was inevitable. Its happened to every coach that's had this group. Why would Ten Hag be any different? Keano had their measure a long time ago. As he said, leopards don't change their spots.
